Here's this week's selection of some of the most interesting new products that have been launched of late.

Cost-Effective IR Sensor Modules Tout Robust Operation

Vishay’s latest fixed-gain infrared (IR) sensor modules offer cost-effective stability for outdoor sensor applications with a typical irradiance of 1.3 mW/m². Provided in compact Minimold packages, the surface-mount TSSP93038DF1PZA and leaded TSSP93038SS1ZA can operate in direct sunlight with enough sensitivity for light barrier applications, unlike high-sensitivity fixed-gain IR sensor modules that require attenuators.

In addition to operating in full sunlight without unwanted pulses, the controlled sensitivity of the Vishay devices eliminates the need for extremely low emitter forward currents, which can lead to unstable intensity outputs. Features include a 260μs reaction time,and a range of 11m is possible in light-curtain applications. Longer ranges can be achieved by using a more focused emitter like the VSLY5940 or by increasing the emitter forward current.

The TSSP93038DF1PZA and TSSP93038SS1ZA operate over a supply voltage range from 2.0V to 3.6V, feature a low supply current of 0.35mA and are sensitive to a carrier frequency of 38kHz. Designed to receive a peak wavelength of 940nm, with shielding against EMI, while an IR filter suppresses visible light.
